Subcapsular cataract dexamethasone

Cagatay Caglar
We report the case of a 72-year-old female who developed macular edema (ME) due to hemicentral retinal vein occlusion in her right eye. A dexamethasone implant was inadvertently injected into the crystalline lens. The patient was followed without repositioning of the dexamethasone implant during the 12 months. Besides, the posterior subcapsular cataract and ME had progressed significantly; hence, cataract extraction and intravitreal ranibizumab injection were performed in the same session. A three-piece intraocular lens was implanted in the sulcus with optic captured, and then intravitreal ranibizumab injection was performed...

BACKGROUND: Granulocyte donors routinely receive dexamethasone orally before donation. Steroids may increase the risk of posterior subcapsular cataract (PSC) formation. STUDY DESIGN AND METHODS: We recruited 100 granulocyte donors (four or more granulocyte donations; any number of platelet [PLT] donations) and 100 age- and sex-matched PLT donors (zero to three granulocyte donations, any number of PLT donations) to examine the risk of PSC. PSC was assessed by a masked ophthalmologist and reading center lens photograph gradings or medical record documentation of PSC as the reason for cataract extraction...

We investigated glucocorticoids-induced alteration of bFGF in AqH, FGFR and beta-crystallin in rat lens epithelial cells (LECs). Results. Data showed dexamethasone had no effect on bFGF in AqH, but reduced FGFR1 in LECs. After six months treatment, cells were detected under posterior capsule in 4/12 lenses. In vitro observations revealed a down-regulated FGFR1 or beta-crystallin by dexamethasone. FGFR in LECs may play an important role in formation of glucocorticoid-induced PSC.

PURPOSE: Treatment with glucocorticoids is a well known risk factor for cataract development, although the pathogenic mechanism has not been elucidated. The aim of the study was to investigate the effects of glucocorticoids in cultured human lens epithelial cells. METHODS: Human lens epithelial cells (HLECs) were exposed to dexamethasone for 24 h. The number of viable cells was determined using the 3-[4, 5-dimethylthiazolyl-2]-2, 5-diphenyltetrazolium bromide (MTT) assay, and proliferation was quantified using Ki-67...

AIMS: Clinically, steroid use is accompanied by a risk for posterior subcapsular cataracts (PSCs). PSC possibly involves perturbation of lens epithelial cell proliferation and differentiation; however, the underlying mechanism is unknown. In this study, we aimed to characterize changes in gene expression in human lens epithelial cells exposed to glucocorticoid using DNA microarray hybridization. METHODS: Human lens epithelial cells (HLE B-3) were treated with dexamethasone (1 microM) for 24 or 48 hours or with vehicle (0...

Dexamethasone-cyclophosphamide pulse (DCP) is the prefered mode of therapy in pemphigus in India because it is relatively free from the side effects seen with heavy doses of daily oral steroids. One hundred forty-six pemphigus patients treated with DCP were observed for side effects of this regimen. One hundred forty mg of dexamethasone was administered IV in 200 ml of 5% dextrose over a period of 60-90 minutes on 3 consecutive days. Five hundred mg of cyclophosphamide was added on first day of the pulse and 50 mg given orally daily in the intervening period...

PURPOSE: A side effect associated with long-term treatment of various diseases with steroids is a high incidence of posterior subcapsular cataracts (PSC). To understand the mechanism underlying steroid-induced cataract, the cultured lens model was developed, and the expression of potential candidate proteins during opacity formation was examined. METHOD: Rat lenses were carefully dissected from the surrounding ocular tissue and incubated in medium 199. Dexamethasone was then added to the medium...

Cataract formation is a deleterious side effect of some hormone therapies, thus, it is important to understand how hormones regulate lens basement structure and function. We have examined the effects of dexamethasone (DEX) on the regulation of Secreted Protein Acidic and Rich in Cysteines (SPARC), fibronectin (FN), and collagen IV (CN IV). To radiolabel newly synthesized proteins, cultured monolayers of bovine anterior lens capsule epithelial (ALCE) cells were pulsed with [(3)H] proline. To identify proteins, an immunofluorescent technique, immunoprecipitation with specific antibodies, and electrophoretic separation on sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) were used...

PURPOSE: Long-term steroid therapy is a known risk factor for the development of posterior subcapsular cataract. Previous work in this laboratory has found soluble lens proteins to bind dexamethasone, but this binding is not due to a glucocorticoid receptor. This study was undertaken to identify the soluble protein or proteins involved in lens glucocorticoid binding. METHODS: Bovine lens extract was incubated with 5.2 x 10(-)(8) M [(3)H]-dexamethasone for 3 hours, and the distribution of label assessed in the soluble and insoluble fractions after centrifugation...
